APL'PABATUVS FOR TAPPING LIQUDS SUCH AS PAINT FROM RECEPTACLES.

Application led July 10, 1924. Serial No. 725,311.

To all whom it may concern: n

Be it known that I, Max Roaman, a citizen of the German Republic, andresiding at Ratingen, Germany, have invented certain new and usefulImprovements in Apparatus for Tapping Liquids Such as Receptacles (forwhich applications for patent have been tiled in -Germany October 26,1922, and August 20, 1923) of which the following is'a specification.

My invention relates-to improvements in apparatus for. tapping liquidssuch as paint from receptacles, and the object of the improvements is toprovide an apparatus by l5 means of which the paint. is stirred beforebeing taken from the receptacle. so that the deposit formed at thebottom is first. mixed with' the body of the liquid and liquid ofhomogeneous composition is withdrawn from the receptacle and a waste ofliquid deposited at the bottom is avoided. 'With this object in view Iprovide apparatus for withdrawing liquid by means of which the liquid isstirred a certain length of time be- '26 vfore it is discharged from thereceptacle.

For the purpose of explaining the invention two examples embodyingthesame have been shown in the accompanying drawings in which the samereference characters have $0 been used in all the views to indicatecorresponding parts. In said drawings,

Fig. 1, is an elevation partly in section showing the apparatus,A

' stirring means, l

Fig. 3 is a sectional .elevation of the means taken on the line 3 3 ofg- Fig. 4, is an elevation partly in section showing a modification` andFig. 5, is a section taken on the line 5-5 of Fig. 4 and Showing therotary pump.

In describing the invention reference will 46 be made to an apparatusfor withdrawing paint from a receptacle. But I wish it to be understoodthat my invention is not limited to such use.

As shown in Figs. 1 to 3. my improved apparatus is mounted on a plate 1adapted to be placed on and secured to the open top of a receptacle 2containing thepaint. Any preferred means may be provided for fixing theplatein position. To show what may be 55 done the plate is formed witharms40 re- Paint from ceiving clamping screws 3 adapted to enga e thereceptacle from the side thereof. It will be understood that the type ofthe said fixing means and the size of the plate. 1 are differentaccordingr to the size 'and form of the receptacle. The plate 1 is fixedto the receptacle so as to close the same in an air tight manner and toprevent loss of paint and spoiling thereof by vaporization and access ofair and impurities.

To the plate 1 a plate 41 is secured which is provided with avertical-bearing 4 disposed axially of .the receptacle and providing aguide for a tubular shaft' 5 passed downwardly therethrough and into thereceptacle to the bot-tom thereof` where it shows a conical end engagingthe bottom and providing an additional support for holding the sameaxially within the receptacle. The bottom part of the shaft '5 carries ahelical stirring member 6 and a transverse arm 7 provided with 'bottomstirring members 8, 9 and 10. As shown the members 8 are in the form ofsprings projecting downwardly and rearwardly from the arm 7 and intoposition for engaging the bottom of the recepacle.. the Imembers 9 arein the form of scratching members jointed to each other, and the members10 consist of upwardly directed sheet metal plates adapted to retard theoperation of the apparatus while stirring the paint. Thr` shaft 5carries a collar 42 fixed thereto by .means of a. screw 12 and adaptedto'be set in different positions for adjusting the shaft 5 in verticalposition and' accommodating the same to receptacles of differentheights: The shaft 5 is adapted to be rotated by means of a bevelgearing 13, 13, a shaft 43 mounted in -bearings 44 and 45 rising fromthe plate 41 and a crank 14 secured to the shaft 43.

Within the tubular shaft 5 there is a nonrotatable pipe 15 secured atits top end by means of a screw 17 to an arm 18 projecting laterallyfrom an upright .46 rising from the plate 41, and it is adapted to beladjusted in vertical direction by means of the screw 17 according tothe height of the receptacle. At its bottom the pipe 15 shows a checkvalve 47 and a plunger 16 provided with a check valve 48 and connectedwith a rod 19, s'aid parts providing a pump for taking paint from thereceptacle. The connecting rod 19 is adjustably connected to a crank pin48 provided on a crank disk 21 the shaft 49 11 bf whith is mounted inthe upright 4.6. The

, connected therewith by means of a clutch that 24, 28, the member 28being adapted 'to be shifted into coupling position by means of acentrifugal governor'49 provided with arms 27 en aging a disk 50carrying the clutch member 28. vThe governor is con-4 fined within acasing 26.

The operation of the apparatus is as follows: For taking paint from-theapparatus the crank 14 is turned and rotary movement is imparted to theshaft 5 and thestirring members 8, 9 and 10. Such rotary movement istransmitted through the gears to the shaft 23 and the governor 49. Afterthe paint hasbeen stirred a certain length' of time the velocity of theapparatus is such the governor shifts the clutch member 28 into couplingengagement with the clutch member 24, whereupon the. pump 16 isoperatedfor raising 15, which paint Hows through a rockable gutter 20. Ifthevelocity of the operation isinsuiicient to' insure proper stirring ofthel paint, or when stopping the pumping altogether, the governor 49permits the member 28 to be disengaged from the member 24, whereupon theoperation of the `pump is interrupted. By4 enclosing the dispensed with,and

governor within the casing 26 the attendant is prevented from closingthe clutch 24, 28 by hand for taking paint fromy the receptacle withoutstirring the same. 7 In the modification shown in Figs. 4 and 5 theclutch 24, 28 and the governor 49 are the pump is alwayls inconnectionwith the stirring and driving mechanism, stirring of' the paint beinginsured by providing a pump, such as a centrifugal pump, which raisesthe paint only after -the mechanism has assumed a certain velocityandthe paint has becomey suiiicient- 1y uent.

At its bottom end, the pipe 15 is formed vwith a casing 30-'having adischarge passage pr ov1ded with a bottom plate 36 :for

dlrectmg the liquid upwardly and into Athe pipe 15. Within the pipethere is a i rotary shaft 32 carrying blades 31 at its .y The shafts 5crank bottom end, said casing, passage, 'blades and shaft providing acentrifugal pump takingthe liquid from the receptacle 2 and raising thesame through the pipe 15. To the top end'of the shaft 32 a .pinion 33 issecured which 1s in mesh with a large `gear 34'keyed to the shaft 23.

and23 are driven from the 14 in the same way as` has'been dewithreference to Figs. Lto 3. For paintfrom the receptacle the crank paintthrough the pipe pump with said operating ,v

means, and 13 14 is turned andthe shafts -5 and 23 are rotated. At firstthe paint is merely stirred and not raised by the pump 31. As the" paintbecomes iuent by stirring the resistance opposed to the stirringmechanism isA reduced andthe speed-of the mechanism and the pump isincreased, until it. is vsutiicient to raise paint through the pipe 15.Shouldv theattendan't fail to turn, the crank 1 4 f ast enough thedischarge of paint is interrupted, so that the paint can be'taken fromthe receptacle only after being suiiciently stirred. While in describingthel invention reference has been made to particular examples embodyingthe same I wish it to be understood that myA invention is not limited`to the constructions shown in thevdrawing, and that various changes maybe made in the general arrangement of the apparatus and` theconstruction of its parts withoutv departing from the invention'.
